Warnings in alert log: WARN: ARC3: Terminating pid 27422864 hung on an I/O operation

[Former Member]

Dear all,

I have the following warnings after upgrading from Oracle 10g to 11g:

WARN: ARC3: Terminating pid 27422864 hung on an I/O operation

WARN: ARC3: Terminating pid 13590640 hung on an I/O operation

krsv_proc_kill: Killing 1 processes (Process by index)

krsv_proc_kill: Killing 1 processes (Process by index)

ARC4: Error 16198 due to hung I/O operation to LOG_ARCHIVE_DEST_2

ARC3: Detected ARCH process failure

ARC3: STARTING ARCH PROCESSES

I know they are safely to be ignored, as the archivelogs shipping is working properly, but how can I get rid of them ?

On my primary  and standby the archive_dest paramater is set normally:

Primary:

SQL> show parameter LOG_ARCHIVE_DEST_2;

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

log_archive_dest_2                   string      SERVICE=PRD_STANDBY COMPRESSIO

                                                 N=ENABLE optional reopen=60 ma

                                                 x_connections=5

Standby:

SQL> show parameter LOG_ARCHIVE_DEST_2;

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

log_archive_dest_2                   string      SERVICE=PRD_PRIMARY COMPRESSIO

                                                 N=ENABLE optional reopen=60 ma

                                                 x_connections=5

Any ideas please ?

Thanks in advance,

J.
